Packaging

Milk Bags

Top Image

Despite every effort that is made to ensure that milk is sterile before it is packaged, it is still vulnerable to microbial deterioration. The role of packaging in this application is to prevent this process, while also protecting the milk from external environmental factors.
As the use of milk packaging made from polymers, rather than glass or cardboard, increases, our solutions both improve packaging production processes and deliver the necessary protection to the packaged goods.

HIGHLIGHTS

Processing Aid

The appearance of packaging is a key factor in a customer’s decision whether to make a purchase. When psroducing at high outputs and with polymers with specialized properties, it can be difficult to achieve stable, defect-free film protection. Our high-quality processing aid enables you to improve the quality of your film, while reducing the amount of energy required in production.

White

Color plays a very important role in protecting milk: white pigments are widely used for their sunlight reflecting properties, while black pigments are used for their ability to absorb heat and provide protection from UV light. These two pigments can be used individually or in combination to achieve maximum performance, while maintaining the desired color visual effect. We can also provide white solution TiO2 free for any application where this pigment cannot be used.

Colors

Milk bags require extreme low-thickness film with high gloss transparency. Colors used for this application must guarantee no defect, while offering a high level of dispersion and diffusion and a low Let Down Ratio. Our wide range of colors can meet these stringent specifications.

Slip

Slip additives make film production easier, by preventing layers of film sticking together, or sliding over each other. However, they must be used with caution. Too much slip agent can cause blooming - reducing transparency, negatively affecting the printing and slipping properties of the film and increasing the risk of low bonding strength on laminated structures. You also need to ensure that the thermal stability of the slip additives used is suitable for the relevant film process conditions. With over 20 years of experience, we can help you avoid these issues.

Anti-Block

Polyolefin film tends to stick together when an attempt is made to separate it into two film layers. This so-called ‘blocking’ is determined by the composition and rolling tension of the film. The quantity and type of anti-blocking agent incorporated into the film to solve this issue can affect transparency, or it can adsorb migrating agents, such as anti-static, slip, or anti-fog additives, decreasing their efficiency. Using our experience, knowhow and synthetic silica (rather than the more commonly used crystalline natural), we can help you avoid these problems.

Slip-Anti-Block

We offer you the advantage of both slip and anti-block additives in one masterbatch, so you can avoid significant adsorption of the migrating slip additives by the anti-block agents. Our range includes several grades suitable for different types of packaging processes, so you get an innovative, agile additive that meets several needs at once.

Processing Aid

Our extensive range of Polymer Process Aid (PPA) masterbatches have been specifically designed to enhance the processability of plastics, such as PE film, pipes and tubes, to improve productivity and quality, and reduce costs.

Antioxidant

Oxidation during extrusion can be avoided by incorporating a secondary antioxidant material, usually phosphates. Long-term aging at temperatures below melting point can be avoided by incorporating primary antioxidant, such as hindered phenols. Thanks to a game-changing additive that we have developed, we can avoid the chemical reaction that inhibits oxidation and degrades polymer chains. Taking into account steps in the extrusion process that can partially consume the added antioxidants, we can create a film recipe to ensure that there is enough antioxidant additive to last for the useful life of the film.
